To all whom t may concern citizen of the United States, residing at FortWayne, in the county of Allen and 'State of Indiana, have inventedcertain new and useful Improvements in Electric Fixtures, of which thefollowing isa specification.

This invention relates to 'an electric fixture for casings to incloseoperating mechanisms, and although particularl. adapted for use inconnection with liquid ispensi'ng pumps, it may have a more general usewherever applicable.

The invention consists in the novel construction, combination andarrangement of the parts. A

In the accompanying drawing- Figure 1 is a side elevation of aninclosing casing to which a fixture of this type is applicable.

Fig. 2 is a sectional view showing the fixture in one position; and

Fig. 3 is a sectional view showing the fixture in an extended position.

This application is a division of my application for dispensingapparatus filed 0ctober 15, 1914, Serial No. 866,759, which has maturedinto Patent 1,248,606, dated December 4, 1917. i

Y In the type of casing to which the present invention is applicable itis desirable to provide a construction which permits a signal lamp to belighted and remain so whether the movable portion of the casing is inraised or lowered position. To accomplish this result itis necessarythat suitable provisions be made between the lixed and movable partswhich will not only accommodate the connecting means, but also willinsure that the connecting means will be returned and maintained in thesame collapsed condition when the movable casing part is closed.

In the present invention the fixture is applied to an inclosing casingwhich comprises a fixed portion 1 and a movable portion 2. Secured tothe fixed portion by means of supporting rods or pipes 3 is a guideplate 4 which is preferably smaller in cross-section than the casingportion 1 to accommodate a reduced upward extension 5 of the movableportion of the casing. This reduced portion 5 lits over the plate 4 andincloses it when the movable portion of the casing is either in raisedor lowered position.

At the top of the reduced portion 5 is a fitting "6 which has an outer'retaining flange 7 in which the edge of a globe 8 is seated, andfastening screws 9 are inserted through the flange against the globe,`or against `,an interposed material 10 for holding the globe in place.This fitting also has a hollow central portion 11 extending above theflange to which a threaded stem 1Q is secured by lock nuts 13 and 14,and supported on the stem is a socket 15 for an electric lamp 16.

Connected through the plate 4 by means of one of the pipes 3 is anelectric connection 17 extending from a source of supply through thesupport to the lamp 16. The electrical connection is preferably in theform of a coil, as shown more clearly in Fig. 2, and at intervals alongthe connection are fastened one or more flexible straps 18 of leather,or other suitable material which hold the connection 17 in both itsextended and collapsed positions. When the movable portion of the casingis in its lowered position the portions of the Hexible members betweentheir fastened points form loops which extend outside or inside of thecoil, as shown in Fig. 2. The extremities of the flexible members 18 aresecured to the lplate 4 and to the projection 11 of the lit-` tangled,and also insure that it occupies the minimum space when in a collapsedcondition.

In operation the movable portion of the casing may be raised or loweredat will, and the electrical connection 17 is correspondingly distended`or collapsed and held in proper position. The lamp 16 is lighted by aswitch at some other point and no attention need be given to anyslidable or moving contacts in order to insure that the lamp may be keptlighted whether the casing is in raised or lowered position.

1. In an electric fixture, the combination with a fixed supportingplate, of a casing slidable thereon and adapted to be raised andlowered, a limp coiled electrical connection extensible between theplate and casing but forming no mechanical connection between them, andmeans comprising parallel flexible straps attached to correspondingpoints of adjacent coils and suspending and conlining the electricalconnection between them, the portions of the straps between theattachment points being folded inwardly between the coils when theconnection is collapsed.4

2. In an electric fixture, the combination` the straps looping withinthe coils when the electrical connection is collapsed.

3. The combination with a xed support-- ing plate, of a slidable casingadapted to be moved up and down on the plate, an electric lamp carriedby theicasing, a coiledlimp electric connection extensible between thelamp and plate to permit movement of the casing, and means includingparallel flexible members attached to corresponding parts of the coilsto hold the electric connection in place.

4. The combination with a iixed supporting plate, of a slidable casingadapted to be moved up and down on the plate, an electric lamp carriedby the casing, and a ilexible limp electric connection from the lamp tothe plate havingno rigidity but extensible to permit movement of thecasing.

In testimony whereof I have signed my name to this speciication, on this17th day of October, A. D. 1917.
